Evidence overview

Every decision MIDAS evaluates produces an evidence envelope. An envelope is a signed, append-only record of:

• What was asked (the decision input).
• Which surface, profile and grant applied.
• What fail-mode policy was effective.
• The outcome (allowed, denied, escalated).
• Why (the rules that fired, the thresholds met or missed).

Evidence is the audit trail. The Explorer surfaces it through the workbench Evidence tab.

See:

• Evidence Envelopes — what each envelope contains.
• Audit Events — derived events emitted from envelopes.
• Integrity — how envelopes are signed and verified.
